Introduction to Smart Contracts
Smart contracts are self-executing contracts with the terms of the agreement directly written into lines of code. They are pivotal in decentralizing finance by automating financial transactions without intermediaries.
How Smart Contracts Work in DeFi
Smart contracts operate on blockchain networks and enforce the terms and conditions programmed into them, enabling direct peer-to-peer transactions and reducing costs.
Benefits of Smart Contracts
- ✅ Automation and efficiency
- ✅ Transparency and security
- ✅ Cross-border transactions
Real-world Use Cases
From token swaps to lending platforms, smart contracts are at the heart of many DeFi applications including decentralized exchanges (DEXs), yield farming, and stablecoins.
